A bomb disposal unit was sent to a recycling centre in Moray after two suspicious items were found.
The Balloch Road facility in Keith was cordoned off when the alarm was raised just after 12.30 on Wednesday.
Police said two items were taken to nearby Blackhillock Quarry as a precaution.
Further investigations into the find are due to take place on Thursday. Moray Council has apologised for any inconvenience caused.
